the above issues related to paint chip wastes. Aiming at evaluation of extent of soils pollution due to heavy metals site survey was carried out at Alang, in the state of Gujarat and Sewri, Mumbai in the state of Maharashtra. Soil as well as paint samples were collected and analyzed for heavy metal content using atomic adsorption spectrophotometer (AAS). The results of soil analysis showed that soils from Alang as well as Sewri were highly contaminated with heavy metals. The reason behind such high contamination could be attributed to the previous ship breaking practice of last 20-25 years. I..................[:=> Show Contents <=:]

is requirement. Experimental data from erosion plots, under natural and simulated rainfall, areused to exemplify how VGT helps maintain soil and water quality. Sediment loads are reduced up to90% in plots with vetiver grass hedgerows compared with those without cover and vetiver hedgerows.Organic matter loads are reduced up to 57% and total P up to 70%. Loads of highly soluble elementslike calcium are not significantly reduced. When VGT is combined with another technology, likeresidue management, risks of failure are diminished.

ion of chitosan/pDNA complexes since transfection efficiency correlates strongly with chitosan Mw. High molecular weight chitosan renders very stable complexes but the transfection efficiency is very low. To improve transfection efficiency, recent studies have examined the use of low molecular weight chitosans and oligomers (Koping-Hoggard M, 2003) in gene delivery vectors. It appears that a fine balance must be achieved between extracellular DNA protection (better with high Mw) versus efficient intracellular unpackaging (better with low Mw) in order to obtain high levels of transfection.

DISADVANTAGES

ADVANTAGES

Cost effectiveness.
High efficiency.
Minimization of chemical/biological sludg,
And regeneration of biosorbent with possibility of metal recovery.


DISADVANTAGES

Early saturation of biomass.
Little biological control over the characteristics of biosorbents.



CONCLUSION

In this case study the removal efficiency of Cadmium was greater than 85%
The adsorption of metal ion on tree leaves reached equilibrium in 60 min.
pH=6-7 and initial concentration of 2mg/L.

sample excavated at about 2m depth was generally a very soft

of about 110% “ 120%


ADVANTAGES


The consolidation period can be reduced by electro osmotic consolidation technique.
The process is very efficient in low permeability clays in which the electro osmotic

permeability is greater than the hydraulic permeability.
Electro osmotic permeability was 200 to 1000 times greater than the hydraulic

permeability.
This method is suitable for local application on small volumes ..................[:=> Show Contents <=:]

ch represents the cyclic loading on the soil. Since 1971, this procedure has been modified and updated. Parallel procedures based on Cone Penetration Test, Shear wave velocity measurements, and Becker Penetration Test was introduced and has been revised and updated. The simplified procedures are based on empirical considerations and have provided useful methods for identifying liquefaction potentials of soils. However, there has been a growing recognition that elementary consideration of the mechanism of liquefaction can provide improved characterization for liquefaction.
